Title: Level indicator for a bulk material hopper - conductive depressions cause sound emitting hammer to rise and fall
IPC: G01F23/22
Filed: 1973-10-12
Abstract: An indicator comprises a motor (1) which drives a paddle (2) through gearing (3).

Title: Two speed drive for spin dryer - has split V-pulley with plunger in end of shaft to release sleeve retaining pins and allow outward movement of balls to force sheaves togeth
IPC: F16H61/662
Filed: 1976-05-12
Abstract: The spin dryer of a washing machine is driven by a V belt from the split pulley (22). One half (19) of the pulley is mounted directly on the shaft (15) which is driven by an electric motor. The other half (21) of the split pulley is mounted on a sleeve (23) which is normally locked to the shaft by radially arranged pins (29). A conical end cover (52) encloses several balls (64) which can move radially outwards due to centrifugal force when a plunger is depressed to release the pins. The outward movement of the balls pushes the half pulley towards the other half pulley. This forces the V belt outwards to increase the effective dia. of the pulley and so increase the speed of the spin dryer.
